D&C 121

 You can feel the Prophet Joseph Smith's remarkably controlled frustration as he writes -

"O God, where art thou? And where is the pavilion that covereth thy hiding place?

2 How long shall thy hand be stayed, and thine eye, yea thy pure eye, behold from the eternal heavens the wrongs of thy people and of thy servants, and thine ear be penetrated with their cries?

3 Yea, O Lord, how long shall they suffer these wrongs and unlawful oppressions, before thine heart shall be softened toward them, and thy bowels be moved with compassion toward them?

4 O Lord God Almighty, maker of heaven, earth, and seas, and of all things that in them are, and who controllest and subjectest the devil, and the dark and benighted dominion of Sheol—stretch forth thy hand; let thine eye pierce; let thy pavilion be taken up; let thy hiding place no longer be covered; let thine ear be inclined; let thine heart be softened, and thy bowels moved with compassion toward us.

5 Let thine anger be kindled against our enemies; and, in the fury of thine heart, with thy sword avenge us of our wrongs.

6 Remember thy suffering saints, O our God; and thy servants will rejoice in thy name forever."  (Doctrine and Covenants 121:1–6)

I have experienced this frustration to a much lesser degree for a much shorter period of time.  I wonder how the Prophet did it.
